Verfahren zur Darstellung der Erythren. Patentiert im Deutschen Reiche vom 25. Juni 1912 ab.Procedure for the representation of the erythrene. Patented in the German Empire on June 25, 1912.
Es wurde gefunden, daß der nach dem Verfahren des Patents 262832 erhältliche Monochlorbutylenglycoläther leicht in Erythren, Chlorwasserstoff und Wasser zerfällt, wenn er der Einwirkung von katalytisch Halogenwasserstoff und Wasser abspaltenden Mitteln ausgesetzt wird; zweckmäßig arbeitet man unter vermindertem Druck. Die Reaktion vollzieht sich nach folgender Gleichung:It has been found that the monochlorobutylene glycol ether obtainable by the method of patent 262832 Easily decomposes into erythrene, hydrogen chloride, and water when under the action of catalytically hydrogen halide and exposure to water-releasing agents; one works appropriately under reduced pressure. The reaction takes place according to the following equation:
CsH17OzCl = 2C4H6 + 2H2O + HCl.
Beispiel 1. C s H 17 OzCl = 2C 4 H 6 + 2H 2 O + HCl.
Example 1.
Man leitet durch ein mit Bariumchlorid beschicktes, auf etwa 350° erhitztes Rohr Dämpfe von Monochlorbutylenglycoläther bei einem Druck von 30 bis 40 mm. In einer gekühlten Vorlage sammelt sich wässerige Salzsäure, während das Erythren als Gas entweicht und als Tetrabromid (Schmelzpunkt 116 °) isoliert werden kann. Die Ausbeute an Erythren beträgt etwa 30 Prozent der Theorie.Vapors are passed through a tube charged with barium chloride and heated to about 350 ° of monochlorobutylene glycol ether at a pressure of 30 to 40 mm. In a chilled Submission collects aqueous hydrochloric acid, while the Erythren escapes as a gas and can be isolated as tetrabromide (melting point 116 °). The yield of erythrene is about 30 percent of theory.
Man leitet durch ein mit Aluminiumoxyd beschicktes, auf 450 bis 500 ° erhitztes Rohr Dämpfe von Monochlorbutylenglycoläther bei einem Druck von etwa 50 mm. Das als Gas entweichende Erythren wird dann als Tetrabromid isoliert. Ausbeute etwa 40 Prozent der Theorie. .It is passed through a tube charged with aluminum oxide and heated to 450 to 500 ° Vapors of monochlorobutylene glycol ether at a pressure of about 50 mm. That as gas escaping erythrene is then isolated as tetrabromide. Yield about 40 percent the theory. .
